// There are a few circumstances where the script is already deleted from SOM but we want to call it.
// Example: onMouseWheelDown() in a script embedded in a customobject and another script.
// another script can hide the customobject and thus the custom object's embedded script gets unloaded.
// the old scriptID is still cached and wants to be invoked! this will lead to an guru but the guru cannot be thrown
// since the ScriptID isn't valid anymore. this leads to a nullpointer assert crash.
